It's great to learn from you. I'm glad you're taking your time and putting a good effort into this. So far you are one of the best I've found.

I watched SO MANY Room "beginner" videos that didn't bother to explain anything. Your video is the first one where I feel like I'm actually being taught how to use Room rather than being told what to type. Thank you SO much. I'm subscribed.

I like how you take your time to explain what the various keywords and syntax means. Thank you so much

I started building my database by your tutorial. I think it is smooth according to your soft instructions. I like the way you teach.

imo this is the best instructor for kotlin programming. Thank u so much for sharing your knowledge!

Best tutorial ever found to learn about room database. Thanks for your efforts.

Amazing tutorial!! Straight to the point cleared my all my doubts

Your content is terrific - everything is clear, short, relevant examples and most importantly nothing superfluous. Recently I found your channel and subscribed because it's hard to find good material. Thank you for your tutorials!

with love from Ukraine, great job, thank you, thanks to you, I finally understood how to work with Room

Thank you for this tutorial series. Very helpful!

the best instructor on whole youtube

very good video, it helped me a lot. greetings from Mexico....... you already have one more subscriber!

I am very happy get very much knowledge about room database in this video. Thanks bro for the tutorial

Your tutorial is really good. Thanks for share with us.

any update on the dependencies? they look different now

Great video. I respect the effort.

wtf dude, i love the way u speak!! thanks btw

Why did you not check whether the INSTANCE field initialized on line 15 is null or not in the synchronized code block in UserDatabase class at 10:00?

Why is it necessary to initialize the database with the init code block every time UserViewmodel is called?

your tutorial is great it's really help me to understand room lib but may you explain why you used coroutines when you insert data only ?

Hey there I'm creating a chat app and I'm storing the chat messages of each person when I click on them but once I have created a room db it is storing the chat messages of all of them . the thing I need is whenever I click one of my friends chat button a specific room db for them has to open which contains only the chat messages of them and mine. Pls help me to solve this.

Thanks for this sir. Very useful

great very simplified tutorial

Excellent video!

Do you have a tutorial that connects an app with a relational database like mysql?

thankyou !! Really merci

Why did you return tempInstance at 9:35 , and not INSTANCE? Same question for return instance, below that Because of @Volatile or you just like it that way?

Teacher, perfect class! I would like a professional opinion from you on the database. For a large app (Airbnb or Uber), using Room for local persistence may be better suited than pure SQLite, right? I ask this because I have no problems writing code using the SQL language. Thank you for your tutorials!

very nice explanation sir...Very usefull video.

Do I have to create tempInstance variable within getInstance function? what happens if I directly use INSTANCE?

Why do we need compile options since we are working with kotlin and not java?

Thank you too Bro Keep Going! ✊✊✊

fucking best teacher that ever found on KZread.

what a great tutorial

Hey man, I really enjoy your video's. Short and concise. But I have a question about reading data from the database. What if I want to read one row and pass the ID into the function. Do I still have to use a coroutine? If yes, how do I return it in the viewmodel method? Or is it OK to not use coroutines when only reading data from the database? Thank you

but in the UserDatabase, if two or more threads invoke getDatabase at the same time, and then they check that tempInstance is null, they all will run synchronized block, in some order, one by one, creating many database instances? Or not?

that's great !

val instance = Room.databaseBuilder( context.applicationContext, userDatabase::class.java, "user name" ).build() i got error this part it said Type parameter bound for T in fun databaseBuilder ( context: Context, klass: Class, name: String ) : RoomDatabase.Builder is not satisfied: inferred type userDatabase! is not a subtype of RoomDatabase!

Really nice explanation of information. I am waiting for next videos on this series. Thanks for these cool videos.

i got an error on Dependencies in line 57 were "kapt "androidx.room:room-compiler:2.3.0""

thanks for the video, i have a question. i read some article that said, we dont need to determine room/retrofit run in background, because the library itself will do by themselve. So in this case we don't need set Dispatcher.IO for insert. what's your opinion ?

@StevdzaSan

2 жыл бұрын

I think that you don't actually need to specify IO dispatcher explicitly, because newer version of ROOM database is using it by default. However I'm always specifying it, because it cannot do any harm either way.

6:30 Why addUser method suspend fun? And why is there no suspend in the readAllData function? Can you explain? Thank you

@user-tl4gu8yh9j

6 ай бұрын

yes on the adduser we are inserting data and on the readalldata we are geeting data 1: it is good practice to use suspend (coroutine) to run the task asynchronously so he is using btw you can use suspend on both method 2: on the readalldata fun we are getting list through the livedata so maybe he ignored but in place of livedata if we are using flow there is no need of suspend cz flow inbuild use suspend but livedata doesnt it is lifecycle aware only

how to check if user is added successfully.?

Please make videos on Dependency injection, Daggar, Daggar 2, Hilt...

I think your synchronized singleton implementation is wrong. When two threads enter at the same time they both pass null check, and they both will try to build instance. Synchronized block should start before null check, actually it may cover the entire function. Only one thread should be able to discover that there is no instance yet, create it and then leave synchronized block. After this other thread(s) will be allowed to enter, and get instance created by first thread.

thanks
